Excellent!
Confirm the skill/setSkill issue fixed, and the 2 second delay before it shows.
A slight personal preference would be that the box disappeared about a second after the cursor is no longer over the word, without having to click in the file. IOW, have it check every second or so whether the cursor is still hovering over the call tip box word, and if not, close the call tip (without clicking on something else).
'Tis a VERY minor thing, though, and unlikely to be worth the effort at coding it.
Great work!
